I'm considering getting an XBox 360 or a PS3 as a media center to use with my Mac, in lieu of an Apple TV, primarily for streaming video. Can anyone give me a rundown of pros and cons? I will require WiFi, and would like DivX playback (which I believe both have?) though most of my library is in MPEG-4 for my iPod anyway. I'm leaning towards the PS3, since A) It's cheaper (considering $99 for a WiFi adapter, and XBox Live costs), B) I'd probably pick up a used one with backwards compatibility and shove the PS2 back in the closet, C) I can slap a 500 GB hard drive in it, and D) It has Blu-ray. But basically, I want to know things that aren't listed on the spec sheet. 1) How well do they work with Macs (assuming I buy the third party software that is out there for it)? 2) How well does streaming media actually work compared to putting it on the local hard drive (i.e. do I want a big hard drive, or should I just stream everything? I only have 802.11g, no N.)? 3) How do the interfaces compare? + any other information that you guys can impart. Thanks for any help.
